FOLKS, CHINESE FRAUDSTERS HAVE ONCE AGAIN COPIED OUR PRODUCT & PLASTERED THESE ALL OVER EBAY, LUCKILY AS USUAL THEY DID A TERRIBLE JOB! THEY ARE USING A CHEAP GRADE OF ALUMINUM ALLOY, THE SAME THAT’S USED FOR WINDOW FRAMES. THEIR TOOLING BARS CRACK RIGHT THROUGH THE BOLT HOLES! DON’T BE FOOLED, BUY QUALITY, BUY OBM.
Start your homebuilt grinder project off with a rock solid tooling arm!
1.5″x1.5″ solid aircraft aluminum tooling arm, 20″ long. It has 2 threaded holes on the one side & 2 unthreaded holes on the side perpendicular to the threaded holes. The threaded holes are for attaching a D-shape backing plate, the unthreaded holes are for attaching a tool rest.
-The front threaded hole is 1.34″ from its center to the front edge of the bar, it’s tapped 1/2-13 straight through the bar
-The second threaded hole is 1.8125″ center to center behind the front threaded hole, it’s tapped 3/8-16 at least 1″ in, enough for the capture bolt
-The front unthreaded hole is .66″ from its center to the front edge of the bar, it’s drilled 3/8″ straight through the bar
-The second unthreaded hole is 1.7″ center to center behind the front hole, it’s drilled 3/8″ straight through the bar
We use these tooling arms on the high quality belt grinders that we manufacture. They work very well with our D-shaped flat platten backing plates & also our tool rests, listed elsewhere. The finish is industrial, we do not paint, polish or anodize these. You can polish them up with a buffing pad if you want a shiny look.
